Molex Optical EMI Shielding Adapters are designed to address mechanical design requirements to limit EMI emissions from the equipment front panel or enclosures. Ideally suited for data communications and networking applications requiring I/O density, Molex EMI adapters are constructed of either all die-cast housings or as a half die-cast, half polymer housing or with EMI shielding polymers. All Molex housings have an EMI gasket that seals the adapters to the panel. The polymer adapter housing provides color coding and significantly increased durability performance. Molex EMI adapters increase the shielding effectiveness while enhancing the front-panel aesthetics compared to traditional plastic adapters.
